Can AC Cause Allergies?
Air conditioners don’t directly cause allergies, but they can worsen symptoms if not properly maintained. Dirty filters, moldy coils, and clogged ducts can circulate allergens such as dust, pollen, and pet dander throughout your home. In some cases, excess moisture inside the unit can promote mold growth, triggering respiratory irritation. Regular cleaning, filter replacement, and humidity control are key to preventing these issues. Keeping your AC system in good condition ensures cleaner air and helps reduce allergy flare-ups.
